i have a h23... but i wanna use an rs-r ex mag exhaust. on the listings, it says they only make it for the h22... so... i'm wondering... is the outlet size on the exhaust manifold from a stock h22 the same as an outlet on a stock h23?... and would it matter if i had headers (DC sports 4-2-1 2-piece) or not... or will i be able to use headers from a h22a also?...

i want an rs-r cause it's quiet... but i don't know if it'll fit on my car.

any help is appreciated. thanks

 

yeah, I would like to know this as well :D

 

I installed the rs*r cat-back for the h22 vtec on my 92 prelude si (h23) without any problems at all. I am using a cheap ebay header and downpipe connected to the stock cat. As long as you are going to use the stock cat or a replacement that has the same flange bolt pattern, you should be golden.

 

nice to know this, i've been wanting to know for a while whether the RS*R would fit on my Si
